NEET BIOLOGY

Detailed explanation-1: -The formation of cytoplasmic projections, or pseudopodia, on the forward edge of the cell, pulling the cell along, is characteristic of the microscopic unicellular protozoans known as amoebas.

Detailed explanation-2: -Pseudopodial morphology includes broad and fan-shaped anterior extensions, finger-like tubular extensions, or a web-like network, the latter are called rhizopods. The shape of the pseudopodia, and the morphology of the enclosing shell or test, when present, are major defining taxonomic characteristics.

Detailed explanation-3: -The polyphyletic heliozoans, or sun protozoans, have radiating pseudopodia (axopodia) that extend like spokes from the central body; microtubules support an outer layer of cytoplasm.

Detailed explanation-4: -Rhizopoda A phylum of the Protoctista that contains the amoebas and cellular slime moulds. They are characterized by the possession of pseudopodia, which are used for locomotion and engulfing food particles. Rhizopods are found in freshwater and marine habitats and the soil.
